WARNING!

Removing the fill cap on a hot enginecan cause scalding coolant to sprayout and burn you badly. If the enginehas been in operation within the previ-ous 30 minutes, be very careful in re-moving the fill cap. Protect face,hands, and arms against escaping flu-id and steam by covering the cap witha large, thick rag. DO NOT try to re-move it until the surge tank cools downor if you see any steam or coolant es-caping. In any situation, remove thecap very slowly and carefully. Be readyto back off if any steam or coolant be-gins to escape.

• Always use wheel chocks or properjack stands to support the vehicle orvehicle components beforeperforming any service work. DONOT work on anything that issupported only by lifting jacks or ahoist. Before resting a vehicle onjack stands, be sure the stands arerated for the load you will be placingon them.

• Before removing or disconnectingany lines, fittings, or related items,relieve all pressure in the air, oil,fuel, and cooling systems. Remainalert for possible pressure whendisconnecting any device from asystem that contains pressure. Highpressure oil or fuel can cause deathor personal injury.

• Always wear protective clothingwhen working on any refrigerantlines and make sure that theworkplace is well ventilated.Inhalation of fumes can cause deathor personal injury. To protect theenvironment, liquid refrigerantsystems must be properly emptiedand filled using equipment thatprevents the release of refrigerantgas. Federal law requires capturingand recycling refrigerant.

• When moving or lifting any heavyequipment or parts, make sure touse proper techniques andassistance. Ensure all lifting devicessuch as chains, hooks, or slings arein good condition and are of thecorrect load capacity. Make sure alllifting devices are positionedcorrectly.

• Corrosion inhibitors and lubricatingoils may contain alkali. DO NOT getthe substance in eyes and avoidprolonged or repeated contact withskin. DO NOT swallow. If ingested,seek immediate medical attention.DO NOT induce vomiting. In case ofcontact, immediately wash skin withsoap and water. In case of harmfulcontact, immediately contact aphysician. Always keep anychemicals OUT OF REACH OFCHILDREN.

• Naptha and Methyl Ethyl Ketone(MEK) are flammable materials andmust be used with caution. Followthe manufacturer's instructions toensure safety when using thesematerials. Always keep anychemicals OUT OF REACH OFCHILDREN.

• When working on the vehicle, bealert for hot parts on systems thathave just been turned off, exhaustgas flow, and hot fluids in lines,tubes, and compartments. Contactwith any hot surface may causeburns.

• Always use tools that are in goodcondition. Make sure you have theproper understanding of how to use

the tools before performing anyservice work. Use only genuinereplacement parts from PACCAR.

• Always use the same fastener partnumber (or equivalent) whenreplacing items. DO NOT use afastener of lesser quality ifreplacements are necessary. (e.g.,Do not replace a 10.9 grade with 8.8grade fastener.)

• Always torque fasteners and fuelconnections to the requiredspecifications. Overtightening orunder-tightening can allow leakage.

• Close the manual fuel valves priorto performing maintenance andrepairs, and when storing thevehicle inside.

• DO NOT perform any repair whenimpaired, tired, fatigued or afterconsuming alcohol or drugs that canimpair your functioning.

• Some state and federal agencies inthe United States of America havedetermined that used engine oil canbe carcinogenic and can causereproductive toxicity. Avoidinhalation of vapors, ingestion, andprolonged contact with used engineoil.

• DO NOT connect the jumperstarting or battery charging cablesto any ignition or governor controlwiring. This can cause electricaldamage to the ignition or governor.

• Coolant is toxic. If not reused,dispose of coolant in accordancewith local environmental regulations.

• California Proposition 65 Warning -Diesel engine exhaust and some ofits constituents are known to theState of California to cause cancer,birth defects, and other reproductiveharm.

• The catalyst substrate located in theDiesel Particulate Filter (DPF)contains vanadium pentoxide, whichhas been determined by the State ofCalifornia to cause cancer. Alwayswear protective clothing and eyeprotection when handling thecatalyst assembly. Dispose of thecatalyst in accordance with localregulations. If catalyst material getsinto the eyes, immediately floodeyes with water for a minimum of 15minutes. Avoid prolonged contactwith skin. In case of contact,immediately wash skin with soapand water.

The stop engine warning lamp willilluminate, and an audible tone will sound,when a major engine problem exists. Yourvehicle will be equipped with one of theindicators above, 1 or 2, depending on theengine model.

WARNING!

If the Stop Engine warning lamp illumi-nates, it means you have a serious en-gine system problem. This should beconsidered an emergency. You shouldstop the vehicle as safely as possibleand turn OFF the ignition. The vehiclemust be serviced and the problem cor-rected before driving again. Failure tocomply may result in death, personalinjury, equipment or property damage.

For engines with the engine-protectionshutdown feature enabled, the stop enginelamp will begin to flash 30 seconds beforethe engine automatically shuts down. Thewarning lamp alerts the operator to theimpending shutdown.

The lamp will also illuminate when the DEFtank is almost empty or the soot level in theDPF is at full capacity. At this level

warning, regeneration cannot be performedand engine power will be derated.

Engine may automatically shut down if thecheck engine lamp and stop engine lampare illuminated and the operator does notcorrect the condition.

Engine Oil Pressure Lamp TurnsOnWhat to do if the engine oil pressure lampturns on.

It is important to maintain oil pressurewithin acceptable limits. If oil pressuredrops below the minimum psi a red

CAUTION

Continuing to operate your vehicle withinsufficient oil pressure will cause seri-ous engine damage. Failure to complymay result in equipment or propertydamage.

• If the oil pressure fails to rise within10 seconds after the engine starts,stop the engine and determine thecause.

• See Engine Oil Specification for thecorrect oil pressure ranges for yourvehicle's engine.

• If the oil pressure suddenly drops,or the audible alarm and engine oilpressure warning light come onwhile driving, do the following:

1. Slow down carefully.2. Move a safe distance off the road

and stop.3. Place the transmission in neutral (N)

and set the parking brake. (SeeParking Brake Valve and Operatingthe Transmission in your vehicle

Operator's Manual, for transmissionshifting and parking brakeinformation.)

4. Turn OFF the engine.5. Turn ON the emergency flasher and

use other warning devices to alertother motorists.

6. Wait a 15–20 minutes to allow oil todrain into the engine oil pan, andthen check the oil level. See EngineOil Level.

7. Add oil if necessary. If the problempersists, contact an authorizedPACCAR engine dealer as soon aspossible.

Check Engine Lamp Turns OnWhat to do if the check engine lamp turnson.

Check Engine Lamp - Turns on when aproblem exists, but the vehicle can still besafely driven. Vehicle should be serviced tocorrect the problem but the situation shouldnot be considered an emergency.

The lamp will also illuminate when a DPFregeneration or addition of diesel exhaustfluid (DEF) is required. For PACCAR PXEngines, this icon may also illuminate if thecrankcase breather element needsattention. Another function of the checkengine lamp is to warn the operator of animpending idle shutdown. When the idleshutdown timer is 30 seconds fromexpiring, the ECM begins flashing thecheck engine warning lamp once persecond. When the timer expires, the ECMwill turn off the warning lamp and shutdown the engine.

Engine is OverheatingThe cooling system may overheat if thecoolant level is below normal or if there issudden loss of coolant. Follow these stepsif the engine is overheating.


12 Y53-1183-1D1 (09/16)

CAUTION

The cooling system may overheat ifthe engine coolant is at the minimumlevel. A sudden loss of coolant,caused by a split hose or broken hoseclamp could also lead to an overheatcondition. Always inspect to ensurehoses and clamps are not cracked,worn, or loose. Failure to comply mayresult in equipment or property dam-age.

NOTE

The system may also temporarily over-heat during severe operating condi-tions such as:

• Climbing a hill on a hot day.• Stopping after high-speed/ high-

load driving.• Debris blocking air flow through

the cooling module (radiator).

If the engine coolant temperature warninglamp comes on and the audible alarmsounds showing an overheat condition, or

if you have any other reason to suspect theengine may be overheating, DO NOTTURN OFF THE ENGINE unless a lowwater warning device indicates a loss ofcoolant. Follow these steps:

Follow these steps if the engine coolanttemperature is rising, or the temperature isalready above normal, and there are noother warning alarms displayed in theinstrument cluster.

1. Reduce engine speed, or stop.When stopped, place thetransmission in neutral (N) and setthe parking brake. Keep the enginerunning. See the vehicle operator'smanual for instructions ontransmission shifting and parkingbrake information.

WARNING!

To reduce the chance of per-sonal injury, vehicle damageand/or death from overheatedengines, which can result in afire, never leave the engineidling without an alert driverpresent. If the engine shouldoverheat, as indicated by the

engine coolant temperaturelight, immediate action is re-quired to correct the condition.Continued unattended opera-tion of the engine, even for ashort time, may result in seriousengine damage or a fire. Failureto comply may result in death,personal injury, equipment orproperty damage.

WARNING!

Removing the fill cap on a hotengine can cause scaldingcoolant to spray out and burnyou badly. If the engine hasbeen in operation within theprevious 30 minutes, be verycareful in removing the fill cap.Protect face, hands, and armsagainst escaping fluid andsteam by covering the cap witha large, thick rag. DO NOT tryto remove it until the surge tankcools down or if you see anysteam or coolant escaping. Inany situation, remove the capvery slowly and carefully. Beready to back off if any steam orcoolant begins to escape.

NOTE

Keep the engine running at idlespeed unless a warning iconturns on and requires an engineto be shut off.

CAUTION

Prolonged periods of idling afterthe engine has reached operat-ing temperatures can decreaseengine temperature and couldcause engine damage from in-adequate lubrication. The nor-mal torsional vibrations gener-ated can also cause transmis-sion wear. An idle shutdownfeature, available on PACCARengines, can be programmed toshut the engine down after aperiod of low idle operation withno driver activity. A flashingwarning lamp will inform thedriver of an impending shut-down. Failure to comply mayresult in equipment or propertydamage.

CAUTION

If the truck is equipped withpower take off (PTO) equip-ment, the engine shutdown sys-tem can be deactivated when

the PTO is operational; howev-er, engine idle periods shouldnot exceed five minutes when-ever possible. Failure to complymay result in equipment orproperty damage.

2. Check to ensure the Oil PressureGauge reads normal.

3. Make sure the engine fan is turningby switching the Engine Fan Switchfrom AUTO to MAN (Manual).

4. Increase the engine speed to aboutone-half of full operating speed, or1,100 to 1,200 rpm, maximum for 2or 3 minutes.

5. Return the engine speed to normalidle. Monitor the enginetemperature. After the temperaturereturns to normal, allow the engineto idle 3 to 5 minutes before shuttingit off. This allows the engine to coolgradually and uniformly.

6. If overheating came from severeoperating conditions, thetemperature should have cooled bythis time. If it has not, stop theengine and let it cool beforechecking to see if the coolant is low.

7. Be sure the vehicle is parked onlevel ground or the readings may be

In somecases, the Malfunction Indicator Lamp(MIL) will activate in conjunction with theHigh Exhaust System Temperature(HEST), Diesel Particulate Filter (DPF) andDiesel Exhaust Fluid (DEF) warning lamps.

NOTE

The malfunction indicator lamp (MIL)will illuminate if the on-board diagnos-tics (OBD) system detects a possibleemissions system failure. The vehicleshould be brought in for service at thenext opportunity to ensure the condi-tion is corrected.

Diesel Particulate Filter (DPF)Warning LampThis warning symbol will appear when theDPF needs to be regenerated and thenalso during the regeneration cycle. Thisicon may also appear if the system isattempting to automatically regeneratewhile the vehicle is in Power Take Offoperation mode.

Engine aftertreatment system includes adiesel particulate filter and DPF warninglamp.

High Exhaust System Temperature(HEST) Warning LampEngine aftertreatment system includes ahigh exhaust system temperature (HEST)warning lamp.

Keep vehicle a safe distance fromcombustible items.

WARNING!

Temperature of the tail pipe, exhaustpipe, the diesel particular filter (DPF) /selective catalytic reduction (SCR) de-vice and surrounding components in-cluding enclosures and steps, will beelevated during and shortly after a re-generation event or normal vehicle op-eration when engine is under high orheavy loading.

If the High Exhaust System Temperature(HEST) warning lamp is on:

• Do not park in an area ofcombustible vapors or materials.You must keep combustibles atleast 1.5 m (5 ft) away from theexhaust (outlet) stream (as it exitsthe tail pipe) while the HEST lamp isilluminated. Always park yourvehicle outside. Failure to do socould ignite an explosion or harmbystanders which could result inserious injury.

• Do not park in an area wherepeople are close by. You must keepcombustibles at least 1.5 m (5 ft)away from the exhaust outlet while

Engine, Wait To StartThis warning icon will appear when thesystem needs some time before attemptingto start the engine.

You may see this appear if the system hasdetected a situation where the starter is toohot and needs to cool down. Alternatively,you may see it when the engine grid heateris on and needs some time to warm up.(PACCAR PX and Cummins ISL engines)

Engine Braking SystemInformation on using the engine brakingsystem.

An engine compression brake is standardon the PX-7 engines. Optionally, thisengine may be equipped with an exahustbrake. When activated, these devicescreate a braking effect on the drive wheels.Because it can help keep your vehicle’sbrakes from overheating, it can save wearand tear on the service brakes. However,the engine compression or exhaust brakeis not an emergency brake or the primaryvehicle brake.


Y53-1183-1D1 (09/16) 17

WARNING!

Do not operate the engine compres-sion brake when driving/operating yourvehicle bobtail or with a loaded or un-loaded trailer on road surfaces withpoor traction (wet, icy, or snow cov-ered roads) or in heavy traffic. Theremay not be enough weight on the rearaxle to provide traction. Brakingcaused by the normal operation of theengine compression brake couldcause you to lose control of the vehi-cle, resulting in an injury accident.Make sure the engine brake is switch-ed "OFF" when bobtailing or with anunloaded trailer. Failure to comply mayresult in death, personal injury, equip-ment or property damage.

WARNING!

The service brakes must be used in anemergency. The engine compressionbrake alone might not stop the vehiclefast enough to prevent an accident.The engine compression brake is NOTintended as the primary brake for the

vehicle, nor is it an emergency brake.The engine compression brake onlyhelps the service brakes by using en-gine back pressure to slow the drive-train. Use the service brakes for quickstops. You could be seriously injured ifyou relied only on the engine compres-sion brake to stop the vehicle in anemergency. Failure to comply may re-sult in death, personal injury, equip-ment or property damage.

CAUTION

DO NOT operate the engine brake un-til the engine oil temperature is above86°F (30°C). Operation below 86°F(30°C) could cause severe damage tothe engine. Idle the engine four mi-nutes at approximately 1000 RPM towarm the engine before activating theengine brakes.

NOTE

If your vehicle is equipped with anti-lock brakes (ABS), operation of thecompression brake (if turned ON) may

be interrupted if the ABS system de-tects wheel-slip due to operation onslippery surfaces.

Ideally (on normal road surfaces), youshould slow your vehicle with thecompression brake (where permitted bylaw) and use the service brakes only forstopping completely. Operating this waywill greatly prolong the life of the servicebrakes.

Compression BrakeProper use of engine compression brakes.

With the compression brake switch ON, thebrake automatically creates its brakingeffect when you remove your foot from theaccelerator pedal.

The brake switch is located on theaccessory dash panel. It controls whetherthe brake is ON (ready to slow the vehicledown) or OFF (no braking action).

1. Do not use the engine compressionbrake to slow the vehicle downwhen you are bobtailing or pullingan empty trailer.

2. Make sure the brake is OFF beforestarting the engine.


18 Y53-1183-1D1 (09/16)

3. After the engine is started, warmedup and you are ready to get underway, turn the engine compressionbrake switch ON for added brakingeffect.

NOTE

If your vehicle is equipped withthe Eaton Vorad® system, oper-ation of the compression brakemay be automatically activated.

Compression Brake ControlsUsing the compression brake controls.

There are two switches on the dash panelthat control the engine compression brake.A master switch turns the system ON orOFF. A second switch, located next to themaster switch, controls the braking effect.This switch allows you to chooseprogressively stronger braking to slow thevehicle down.

Engine compression brake controlsinclude:

• ON/OFF switch• Three-position selector switch• Clutch switch

• Throttle sensor• Service brake pressure switch• Eaton Vorad® Anti-Lock Braking

System

Engaging conditions for the enginecompression brake:

• Engine speed must be above 1,000RPM.

• Coolant temperature must be above59°F (15°C).

Deactivation conditions for the enginecompression brake:

• Accelerator pedal is depressed.• Clutch pedal is depressed.• Engine speed falls below 800 RPM.• ABS control is active.• ECM recognizes a system problem.

CAUTION

Operating the engine with a compres-sion brake that will not automaticallydeactivate (i.e. when the dash switchis OFF, clutch pedal is depressed orthrottle is applied) will cause severe in-ternal engine damage. Do not operate

the engine if the compression brakewill not deactivate. Failure to complymay result in equipment or propertydamage.

Engine Compression Brake LevelSwitch OperationHow to operate the compression brake.

There are two switches that control yourvehicle’s engine compression brake. Oneswitch turns the system ON/OFF and thesecond switch controls the braking level.These switches are located on the dashswitch panel.

For the three-position engine compressionbrake level switch, there will be 100percent engine braking when the switch isin the up (HIGH) position. In the middle(MEDIUM) position, there will be 66percent engine braking. In the down (LOW)position there will be 33 percent enginebraking.

With the compression brake switch ON, thecompression brake will be engaged whenthe service brake is applied. If the cruisecontrol is operated in conjunction with thecompression brake, the compression brake

DrivingIntroduction and important informationabout operating your vehicle safely.

Correct care of your engine will result inlonger life, better performance, and moreeconomical operation.

Follow the daily maintenance checks listedin Engine Maintenance on page 33.

The new PACCAR engine associated withthis manual does not require a “break-in”procedure. This section of the manualprovides all of the necessary informationrequired for proper engine operation.

Check the engine oil pressure and enginecoolant gauges, warning lamps, and othergauges daily to make sure they areoperational. Normally each gauge willmake a full sweep when ignition key iscycled ON to indicate that the gauge isoperating correctly.

1 Do Not Use Combustible Gas in Turbo

NOTE

Numerous safety devices (i.e. engineshutoff devices) are available to mini-mize the risk of engine overspeedingcaused by combustible vapors beingingested into the air intake system.

PACCAR recommends the installation ofan air intake shutoff device or a similarsafety device to minimize the risk ofoverspeeding, as can occur when thevehicle is being operated in a combustibleenvironment, such as from a fuel spill orgas leak.

WARNING!

Combustible vapors near the air intakesystem could be ingested into the en-gine, causing the engine to suddenlyaccelerate and overspeed. This condi-tion could result in operator losing con-trol of the vehicle if an unexpected in-crease in engine RPM occurs. Com-bustible vapors could also cause a fire.

Do not operate your vehicle in an areawhere combustible chemicals or va-pors may be present. Failure to com-ply may result in death, personal in-jury, equipment or property damage.

NOTE

IT IS THE RESPONSIBILITY OF THEOWNER AND OPERATOR TO OPER-ATE THE VEHICLE IN A SAFE ENVI-RONMENT.

NOTE

Cold Weather StartingSteps for starting the engine in coldtemperatures.

Allow the Wait to Start warning lamp toturn off. Engine, Wait To Start on page 17

Follow this engine starting procedure whenthe outside temperature is below 50° F(10° C).

CAUTION

To reduce the possibility of damage tothe lubricating oil pan, due to the ma-terials used in the manufacture of thelubricating oil pan, under no circum-stances should an external heatsource be applied directly or indirectlyto the lubricating oil pan.

1. Follow the Normal StartingProcedure on page 22.Refer to the vehicle operator'smanual instructions for anyadditional cold weather startingprocedures.

2. If starting a cold engine, slowlyincrease the engine speed. Thisprovides adequate lubrication to the

bearings and gives ample time toallow the oil pressure to stabilize.

CAUTION

The use of starting aids, suchas ether, may result in damageto the engine and aftertreat-ment system.

If an engine must idle for an extendedperiod of time, it should be done at a fastidle (1,000 RPM maximum) at coolanttemperatures below 150°F (70°C).

3. For coolant temperatures below150°F (70°C), use a low gear anddrive at moderate engine speeduntil the engine coolant has reachedoperating temperature. Do not letthe engine idle longer thannecessary.

CAUTION

Do not operate the engine atlow idle for long periods of timewhen the coolant temperatureis below the normal operating

range. This could result in thefollowing:

• Fuel dilution of the lu-bricating oil.

• Carbon buildup in thecombustion chamber.

• Sticking of the valvesin the cylinder head.

• Reduced performance.• Damage to aftertreat-

ment components.

Starting Procedure After ExtendedShutdown or Oil ChangeGuideline on starting the engine afterprolonged shutdown or oil change.

After extended shutdown or an oil changefollow the Normal Starting Procedure onpage 22.

The engine will run at idle only until theminimum oil pressure is detected by theECM. It can take more cranking time tostart the engine after an extended shutdown or oil change.

Operating the EngineAfter the engine starts:

Monitor the oil pressure and coolanttemperature gauges frequently. Refer to Engine Oil Specifications on page 43 and Engine Coolant Specifications on page48 for recommended operating pressuresand temperatures. Shut off the engine ifany pressure or temperature does NOTmeet the specifications.

Continuous operation with engine coolanttemperature above or below the enginecoolant temperature specifications listed in“Engine Coolant Specifications on page48” can damage the engine.

Engine Operating RangeInformation on operating the engine atproper RPM.

Proper Engine Operating Range

1. Full Throttle RPM2. Peak Torque

CAUTION

Operating the engine at full throttle be-low peak torque will shorten engine lifeto overhaul, can cause serious enginedamage, and is considered engineabuse. DO NOT operate the engine atfull throttle operation below peak tor-que RPM for more than 30 seconds.

Failure to comply may result in equip-ment or property damage.

PACCAR engines are designed to operateat full throttle under momentary conditionsdown to peak torque engine speed. This isconsistent with recommended operatingpractices.


24 Y53-1183-1D1 (09/16)

CAUTION

Operating the engine beyond the max-imum engine speed can cause severeengine damage. Use proper operatingtechniques for the vehicle to preventengine overspeed. See Engine Speci-fications for maximum engine speed.Failure to comply may result in equip-ment or property damage.

Idling Time

1. Engine Idle RPM

CAUTION

DO NOT idle the engine for excessive-ly long periods. Long periods of idling,

more than 10 minutes, can cause poorengine performance.

NOTE

For applications with high idle-time, tohelp reduce soot loading in the after-treatment system, avoid long periodsof idling. If idling is required, increaseidle-speed using the cruise controlfunction.

Engine ShutdownBefore stopping the engine follow theseprecautions.

NOTE

DO NOT shut off the engine immedi-ately. A hot engine stores a greatamount of heat and it does not cooldown immediately after it is shut off.Always cool the engine down beforeshutting it off. You will greatly increaseits service life.

Idle the engine at 1,000 RPM for fourminutes. Then low idle for 30 seconds

before shutdown. This will allow circulatingcoolant and lubricating oil to carry heataway from the cylinder head, valves,pistons, cylinder liners, turbocharger, andbearings. This way you can prevent enginedamage that may result from unevencooling.

NOTE

For engines equipped with an elec-tronic control module (ECM) ensurethe key switch is turned OFF for a min-imum of 70 seconds prior to discon-necting the continuous (unswitched)battery power supply. If the unswitchedbattery power supply is disconnectedin less than 70 seconds after the keyswitch is turned OFF, active fault co-des and incorrect ECM informationcan occur.

CAUTION

Failure to follow the correct shutdownprocedure may result in damage to theturbocharger and shorten the turbo-charger life.

Electromagnetic InterferenceInformation on electromagneticinterference (EMI).

If not installed correctly, some vehicleaccessories (CB radios, mobiletransmitters, etc.) can generate and useradio frequency energy that may causeelectromagnetic interference (EMI)between the accessory and theelectronically controlled fuel system. Underthese conditions, PACCAR is not liable forany performance problems with either thefuel system or the accessory. EMI is notconsidered by PACCAR to be an enginefailure and therefore is not warrantable.

System EMI SusceptibilityPACCAR products are designed andtested for minimum sensitivity to incomingelectromagnetic energy. The fuel systemEMI susceptibility has been designed witha high tolerance against EMI and in mostnormal circumstances, if not all,electromagnetic energy-emitting devicesthat meet the Federal CommunicationsCommission legal requirements shouldcause no interference.

System EMI Radiation LevelsElectronic components are required topass various PACCAR and industry EMIspecifications. Our testing has shown thatwhen the engine is properly installed andmaintained, it will not interfere with properlyinstalled onboard communicationequipment.

If any interference condition is noticed,follow these suggestions to reduce theamount of EMI:

1. Locate the accessory receivingantenna further away.

2. Check with the accessory supplierrepresentative in your area to:

• Accurately calibrate theaccessory for proper frequency,power output, and sensitivity.

• Determine the optimum antennalocation by obtaining antennareflective energy datameasurements.

• Ensure that the optimumantenna type and mountingarrangement is being used.

• Ensure the accessory equipmentis properly constructed for

maximum filtering to rejectincoming electromagnetic noise.

WARNING!

Do not operate the engine compres-sion brake when driving/operating yourvehicle bobtail or with a loaded or un-loaded trailer on road surfaces withpoor traction (wet, icy, or snow cov-ered roads) or in heavy traffic. Theremay not be enough weight on the rearaxle to provide traction. Brakingcaused by the normal operation of theengine compression brake couldcause you to lose control of the vehi-cle, resulting in an injury accident.Make sure the engine brake is switch-ed "OFF" when bobtailing or with anunloaded trailer. Failure to comply mayresult in death, personal injury, equip-ment or property damage.

WARNING!

Do not use the engine brake when op-erating on road surfaces with poortraction (such as wet, icy, or snow cov-ered roads or gravel). Retarders cancause the wheels to skid on a slipperysurface. You could lose control of thevehicle and/or jackknife if the wheelsbegin to skid, resulting in an accident.Failure to comply may result in death,personal injury, equipment or propertydamage.

CAUTION

The engine ECM maintains a record ofmaximum RPM. Exceeding the maxi-mum RPM will be considered driverabuse and will affect the engine war-ranty. See Engine Spcifications.

WARNING!

DO NOT use an exhaust brake whendriving bobtail or with an unloadedtrailer. There may not be enoughweight on the rear axle to provide trac-tion. This could cause a loss of controland jackknife resulting in an injury ac-cident. Make sure the exhaust brake isswitched “OFF” when bobtailing orwith an unloaded trailer. Failure tocomply may result in death, personalinjury, equipment or property damage.

CAUTION

Never exceed governed engine speedbecause engine damage can occur.Operating engine beyond the gov-

erned speed causes additional strainon valve train and internal engine com-ponents. Operate the engine withingoverned engine speed.

NOTE

Once you have determined what thesafe speed is for your vehicle, operatethe engine brakes with the transmis-sion in the lowest gear that will notcause the engine speed to exceed therated engine speed. The optimumbraking power of the engine brakes isreached at rated engine speed. Cor-rect gear selection, therefore, is criti-cal.

The selector switch can be used to varybraking power as road conditions change.

Tips for Operation on Slick Roads

WARNING!

To reduce the possibility of personalinjury or property damage, always al-low for extra distance between yourvehicle and other objects when usingthe service brakes or engine brakes onslick roads.

The operation of any vehicle is difficult topredict on slick roads. The first 10 to 15minutes of rainfall are the most dangerous,as road dirt and oil mixed with rain create avery slippery surface.

WARNING!

Do not use any of the vehicle’s retard-ers in any situation that requires an im-mediate stop and/or in situations ofpoor traction (such as wet, icy or snowcovered roads). Trying to use the re-tarder instead of the service brakesmay cause a loss of vehicle control,which may result in an accident involv-ing death or personal injury.

When driving on slick roads, start with the“ON/OFF” switch in the “OFF” position andthe two-position selector switch in the“LOW” position. If your tractor is equippedwith a twin-screw rear axle, position thepower divider switch in the “unlocked”position. Remove your foot from theaccelerator pedal to make sure the vehiclewill maintain traction with the retardingpower of the engine alone. If the vehicledrive wheels begin to skid or if there is afishtailing motion, DO NOT activate theengine brakes. If traction is maintainedusing the retarding power of the enginealone and more braking power is required,switch the two-position selector switch tothe “LOW” position and activate the enginebrakes by switching the “ON/OFF” switchto the “ON” position. If the vehicle’s drivewheels begin to skid or there is a fishtailingmotion, switch the “ON/OFF” switch to the“OFF” position. If traction is maintainedwhen the engine brakes are activated andmore braking power is required, move thetwo-position selector switch to the “HI”position. Again, if the vehicle has losttraction or if there is a fishtailing motion,switch the “ON/OFF” switch to the “OFF”position. DO NOT attempt to use theengine brakes in the “HI” position.

Engine MaintenanceIntroduction and important maintenancerequirements.

PACCAR recommends that the engine bemaintained according to the maintenanceschedule in this section.

If the engine is operating in ambienttemperatures below 0°F (-18°C) or above100°F (38°C), perform maintenance atshorter intervals. Shorter maintenanceintervals are also required if the engine isoperated in a dusty environment or iffrequent stops are made.

Some of these maintenance proceduresrequire special tools or must be completedby qualified personnel. Contact your localPACCAR authorized repair location fordetailed information.

If your engine is equipped with acomponent or accessory not manufacturedby PACCAR Inc, refer to the component

manufacturer's maintenancerecommendations.

WARNING!

Never idle your vehicle for prolongedperiods of time if you sense that ex-haust fumes are entering the cab. In-vestigate the cause of the fumes andcorrect it as soon as possible. If thevehicle must be driven under theseconditions,drive only with the windowsopen. Failure to repair the source ofthe exhaust fumes may result in death,personal injury, equipment or propertydamage.

WARNING!

Exhaust fumes from the engine con-tain carbon monoxide, a colorless andodorless gas. Do not breathe the en-gine exhaust gas. A poorly maintained,damaged or corroded exhaust systemcan allow carbon monoxide to enterthe cab. Entry of carbon monoxide intothe cab is also possible from other ve-hicles nearby. Failure to properly main-tain your vehicle could cause carbon

monoxide to enter the cab, resulting indeath or personal injury.

NOTE

Keep the engine exhaust system andthe vehicles cab ventilation systemproperly maintained. It is recommend-ed that the vehicles exhaust systemand cab be inspected (1) By a compe-tent technician every 15,000 miles(24,140 km) (2) Whenever a change isnoticed in the sound of the exhaustsystem (3) Whenever the exhaust sys-tem, underbody, or cab is damaged.

PACCAR is not responsible for problemscaused by non-genuine filters that do notmeet PACCAR performance or durabilityrequirements.

Contact your local PACCAR authorizedrepair location for specific part numbers.

Fleetguard filters are standard on newPACCAR engines. PACCAR recommendstheir use.

Fleetguard products meet all PACCAR teststandards to provide the quality filtrationnecessary to achieve the engine's designlife. If other brands are substituted, thepurchaser should ensure the filterspecification meet or exceed theFleetguard specifications.

CAUTION

Use of non-genuine oil filters cancause severe engine damage.

Engine Lubricating OilRecommendations andSpecifications

PACCAR engine oil type, viscosity, andadditives.

A major factor in maintaining engineperformance and durability is the properuse of quality engine lubricating oils usedin conjunction with the appropriate oil drainand filter change intervals. Attempting toextend the oil and filter change intervalbeyond the manufacturersrecommendations may decrease enginelife due to factors such as corrosion,deposits, and wear.

See Engine Lubrication and Filter Intervalsto determine which oil drain interval to usefor an application.

NOTE

It is the operator’s responsibility to fol-low these recommendations to ensure

that the engine warranty is not affect-ed.

The primary PACCAR recommendation isfor the use of SAE 10W-30 API CK-4 orCJ-4 multigrade lubricating oil for normaloperation at ambient temperatures above5°F (-15°C). For ambient temperaturesbelow 5°F (-15°C) SAE 5W-30 may beused, provided it meets API CK-4 or CJ-4oil specifications and biodiesel or biodieselblended fuel is not used as fuel for theengine. Use of 0W-40 and 0W-30 syntheticoils that meet API CK-4 or CJ-4certification can be used in operationswhere the ambient temperature neverexceeds 0°C (32°F). 0W-40 and 0W-30 oilsdo not offer the same level of protectionagainst fuel dilution as do highermultigrade oils. Higher cylinder wear canbe experienced when using 0W-40 or0W-30 oils in highload situations. Using amultigrade oil helps improve enginecranking in low-temperature conditions,reduces deposit formation and increasesengine durability. The use of a fueleconomy oil such as an API FA-4 oil is notapproved for this engine.

NOTE

If the type/oil capacity of each lubricat-ing oil pan is not known:

• Contact a PACCAR® AuthorizedRepair Location.

• Determine the capacity of the oilpan option for the engine beingserviced by using QuickServe™Online and the engine serialnumber.

• Fill the lubricating oil pan to thesmallest oil pan capacity listed forthe engine being serviced. Thenadd 1 qt (0.95 liters) of oil at atime until it reaches the high markon the dipstick. Record the num-ber of liters/quarts added, so thecapacity is known the next timethe oil is drained.

NOTE

Any of the oil weights listed in thechart above are acceptable to use aslong as the oil meets API CK-4 oilspecifications.

New Engine Break-In OilsPACCAR does not approve the use ofspecial “break-in” engine lubricating oils fornew or rebuilt PACCAR engines. It is

recommended to use the same lubricatingoil for engine break-in that will be usedduring normal operation.

CAUTION

A sulfated ash limit of 1.85 percent hasbeen placed on all engine lubricatingoils recommended for use in PACCARengines. Higher ash oils can causevalve and/or piston damage and leadto excessive oil consumption. Failureto comply may result in equipmentdamage.

CAUTION

The use of a synthetic-base oil doesnot justify extended oil change inter-vals. Extended oil change intervalscan decrease engine life due to factorssuch as corrosion, deposits, and wear.Failure to comply may result in equip-ment damage.

Aftermarket Oil Additive UsagePACCAR does not recommend the use ofaftermarket oil additives. Today's high-quality engine lubricating oils are very

sophisticated. Most oils already containprecise amounts of additives blended intothe lubricating oil to meet stringentperformance requirements.

These oils meet performancecharacteristics that conform to the lubricantindustry standards and are sufficientprotection when used according to therecommendations. Aftermarket lubricating

oil additives are not necessary to enhanceengine oil performance and may in somecases reduce the oil's capability to protectthe engine.

Engine Lubrication andFilter Intervals

Oil change intervals for normal and severeduty applications.

The intervals are based on the vehiclesaverage speed/miles per hour (mph).(Which includes idle time.) Locate yourvehicles average vehicle speed/mph in thefirst column to determine the oil change/filter change interval to use. If the vehicle isequipped with an hour meter, it isacceptable to use the engine hours listedfor the oil change and oil filter changeinterval. If the average vehicle speed/mphis unknown and the vehicle is not equipped

with an hour meter use the last column inthe table that fits the application or connectan electronic service tool. The electronicservice tool can provide the averagevehicle speed recorded by the enginecontrol module (ECM). This can be done atan Authorized Engine Repair Location.

See the following table to determine themaximum recommended oil change and oilfilter change intervals in kilometers [miles]/hours or months, whichever comes first.

CAUTION

Extending the oil and filter change in-terval beyond the recommendationswill decrease the engine life due tofactors such as corrosion, deposits,and wear. Engine oil filters capture dirtand remove deposits from the oil to

prolong the life of internal moving com-ponents. Follow the oil and filterchange intervals as recommended inthis section of the manual. Failure tocomply may result in equipment orproperty damage.

NOTE

If B6-B20 biodiesel fuel is used, the oiland filter must be changed every40,000 mi (64,000 km) for line haul ap-plications; every 20,000 mi (32,000km) for severe duty, or every sixmonths.

WARNING!

Coolant is toxic. DO NOT get the fluidin eyes. If contact occurs, flood eyeswith large amounts of water for 15 mi-nutes. Avoid prolonged or repeatedcontact with skin. In case of contact,immediately wash skin with soap andwater. DO NOT take internally. If swal-lowed, seek immediate medical atten-tion. DO NOT induce vomiting. Failureto comply may result in death, person-al injury, equipment or property dam-age.

CAUTION

The engine cooling system has veryspecific maintenance and inspectionrequirements. Failure to follow require-ments can damage the engine. Enginedamage can include but is not limitedto freezing, boiling, corrosion, pittedcylinder liners. This information isfound in the engine manufacturersowner’s manual. It is the owner’s re-sponsibility to follow all requirements

listed in the engine manufacturersowner’s manual.

NOTE

Coolant is harmful to the environment.Unused coolant must be stored as atoxic hazardous material in leakproofcontainers. Used coolant must beprocessed as industrial chemicalwaste. Please follow HAZMAT guide-lines with both used and unused cool-ants.

ConcentrationCheck the level of freeze/boiloverprotection, which is determined by the ELCconcentration. Use a glycol refractometerto determine glycol level. Add ELC toobtain the ELC/water ratio required toprovide the protection you need. A 50/50mix of ELC and water is adequate for mostapplications. For extremely cold operatingconditions, the ratio can be adjusted to ahigher concentration of ELC.

NOTE

Maximum recommended ELC concen-tration is 60% ELC and 40% water byvolume (a 60/40 coolant mixture). Theminimum recommended concentrationis 40%.

ConditionPerform a visual inspection of the ELC. Itshould have no cloudiness or floatingdebris. Determine the chemical inhibitorconcentration level by using an ELC-specific test kit or test strips. Inhibitorconcentration level determines corrosionprotection. If you are concerned aboutpossible coolant quality, contamination, ormechanical problems, submit a coolantsample for analysis. Improper maintenancemay cause coolant degradation and couldresult in damage to the cooling system andengine components. Consult your dealer orthe ELC manufacturer’s representative forrecommended ELC test kits, test strips,and laboratory sample procedures.

Fuel Recommendations

Precautions and recomendations forselecting and using the right diesel fuel.

WARNING!

The use of diesel fuel that has beenmixed with other fuels may cause anexplosion. DO NOT mix gasoline, alco-hol, or gasohol with diesel fuel. Makesure you know your fuel source anduse the recommended diesel fuel asindicated in this section of the manual.Failure to comply may result in death,personal injury, equipment or propertydamage.

CAUTION

Dirt or water in the fuel system cancause severe damage to both the fuelpump and the fuel injectors. Due to theprecise tolerances of diesel injectionsystems, it is extremely important thatthe fuel be kept clean and free of dirtor water. Know your fuel source andmake sure all steps are taken for dis-pensing or using clean fuel in your ve-hicle. Failure to comply may result inequipment or property damage.

CAUTION

Unapproved fuel can reduce economyor possibly damage fuel system com-ponents. Unapproved fuels typically donot have enough lubricity elements inthe fuel to properly lubricate the fuelinjection system. Be sure you followthe fuel recommendations as indicatedin this section of the manual. Failure tocomply may result in equipment orproperty damage.

CAUTION

Using diesel fuels blended with lubri-cants may cause damage to your ex-haust aftertreatment system. Serviceintervals for aftertreatment systemswill be reduced. DO NOT use dieselfuel blended with lubricating oil in en-gines equipped with an aftertreatmentsystem. Failure to comply may resultin equipment or property damage.

ENGINE MAINTENANCE - Fuel Recommendations

Y53-1183-1D1 (09/16) 49

2

CAUTION

DO NOT use high-sulfur diesel fuel asit will damage the exhaust aftertreat-ment system. Also, the engine will notmeet emission regulations. Use onlyultra-low-sulfur diesel (ULSD) fuel.Failure to comply may result in equip-ment or property damage.

CAUTION

If ultra-low-sulfur diesel (ULSD) fuel isnot used, the engine may not meetemission regulations, and damagemay occur to the exhaust aftertreat-ment system. The use of high-sulfurdiesel fuel will damage the exhaust af-tertreatment system and impact theengine emission. ULSD fuel is re-quired for correct operation of the af-tertreatment. The engine has been op-timized for use with an aftertreatmentsystem together with ULSD fuel tomeet the 2013 U.S. EnvironmentalProtection Agency regulations. Failure

to comply may result in equipment orproperty damage.

NOTE

PACCAR recommends that the cetanenumber of diesel fuel be a minimum of45 for engines that are expected to op-erate at temperatures below 32ºF(0ºC) and a minimum of 42 for enginesthat are operated at temperaturesabove 32ºF (0ºC).

Using diesel fuel with a lower-than-recommended cetane number can causehard starting instability, and excessivewhite smoke. To maintain satisfactoryoperation at low ambient temperatures, it isimportant to specify diesel fuel of thecorrect cetane number.

PACCAR requires all permissible fuels tohave adequate fuel lubricity. Lubricity canbe determined by ASTM, specificationD6079, ISO 12156, High FrequencyReciprocating Rig (HFRR) in which the fuelmust have a wear scar diameter of 0.02 in.(0.5 mm) or less.

The use of Ultra-low-sulfer-diesel (ULSD)fuel is required for this engine in order tomeet emission regulations and to preventdamage to the engine and exhaust system.The use of other grades of diesel fuelsother than ULSD fuel will be considered ause of incorrect fuel for the engine.PACCAR is not responsible for failurescaused by the use of incorrect fuel, oil orDEF or by water, dirt or other containmentsin the fuel or DEF.

Warranty and the Use ofBiodiesel Fuel

Biodiesel information and warrantyprecautions.

PACCAR Inc. approves the use ofbiodiesel fuel blends from 6 to 20 percentby volume in diesel fuel providing that thefollowing conditions are met:

• The biodiesel used in the blendmeets ASTM Standard D 6751 orEN 14214 specifications.

• The biodiesel used in the blend issourced from a BQ-9000 AccreditedProducer.

ENGINE MAINTENANCE - Warranty and the Use of Biodiesel Fuel

50 Y53-1183-1D1 (09/16)

2

• The finished blend meets the fuelproperties of the ASTM StandardD975 (up to B5 blend) or D7467 (B6to B20 blend).

• The engine oil and oil filter arechanged per the modified schedule.See the Engine PreventativeMaintenance Schedule.

• The fuel filter is changed every25,000 miles/40,000 km.

The use of approved biodiesel fuel doesnot affect the PACCAR engine warranty.Failures caused by the use of non-approved biodiesel fuels or other fueladditives that are of unacceptable qualityor do not meet specified industry standardsare not considered as defects of parts orworkmanship by PACCAR and thereforewill not be covered by the PACCAR enginewarranty.

PACCAR recommends that customersintending to use biodiesel blends becomefamiliar with the additional handlingconsiderations of these fuels such asageing, metal compatibility and tendency toabsorb water. Please reference the fuelsupplier’s technical information or industryguidelines such as the American TruckingAssociation Truck Maintenance Councildocument RP 357.

In particular, operators should be awarethat biodiesel blends are more prone tocold flow (gelling) and filter plugging issuescompared to conventional diesel fuel. Ifvehicles are expected to be operated intemperatures below freezing, care shouldbe taken to ensure that both the biodieselfuel used and the appropriate vehicle fuelsystem accessory heaters are utilized.

Operators should also be aware thatbiodiesel energy content (by volume) islower than diesel which can reduce fueleconomy by up to two percent.

Recommendations toAvoid Fuel Gelling

Information to prevent fuel gelling.

• Use appropriate fuel grade/blend forconditions.

• Specify vehicle with proper coldweather equipment (12v electricpre-heater, fuel blending valve, fuelcoolant heater, 12v line heaters andtank heaters).

PACCAR does not recommend the use offuel additives, however, should a customer

decide there is a need for temporary use ofa winter fuel additive, PACCAR offers thefollowing guidance:

• Use an industry known, high qualityproduct (EPA approved).

• Only use the additive for theminimum time needed.

• Follow additive manufacturer'sinstructions exactly.

• Refuel with proper grade fuel assoon as possible.

Fuel Filter Interval

Replace the fuel filters (pressure andsuction side) at the same interval as the oiland oil filter are changed. EngineLubrication and Filter Intervals on page 44

Fuel FilterImportant information on replacing enginemounted cartridge type fuel filters.

Perform these maintenance proceduresaccording to the Preventative MaintenanceSchedule.

WARNING!

When removing the fuel filter, a quanti-ty of fuel will escape. Do not smoke orallow an open flame in close proximity.Failure to do so could ignite a fire orcause an explosion which could resultin serious injury to you and/or bystand-ers. Failure to comply may result indeath, personal injury, equipment orproperty damage.

NOTE

The fuel filter and the hand pump arelocated on the left-hand side of the en-gine, as viewed from the driver's seat.

NOTE

Use of poor quality fuel may requiremore frequent fuel filter element serv-ice.

DescriptionThe fuel filter/water separator moduleprovides fine-particle filtration, waterseparation, water-in fuel-sensing,automatic water draining, lifetimepurification of drained water with acharcoal filter, 12V preheating and systemmanual priming in a singular easy toservice module.

Replace the suction side and the pressureside fuel filters at the same time. It isrecommended to replace the fuel filters atthe same interval as the oil and oil filter arechanged. If the oil drain interval being usedis greater than 15,000 mi (24,000 km), asdetermined by the Engine Lubrication andFilter Intervals, the fuel filter change can beextended until the oil drain interval.

NOTE

The engine and fuel module should beoperated in cold climates with accepta-ble cold climate fuel blends which no-ticeably reduces wax gelling in the fuelfilter cartridge. The fuel module in-cludes a 12V preheater to support pre-heat of the fuel for initial start-up inmild climates. Failure to operate withacceptable cold climate fuel may resultin insufficient fuel flow to the fuel injec-tion system.
